There are girls who go astray when they meet a man. Mio, a college student at a highly prestigious young lady's college, is one such girl. Perhaps it was because she was immune to men because she went to an all-girls' college that she became addicted to hostesses. In order to pay for men, Mio started going to high-class date clubs. It didn't take her long to be noticed by a regular customer and asked for sex. The (former) young lady who provides sexual services to a man as old as her stepfather is truly intriguing.
